Two distinct kinetic regimes for the relaxation of light-induced superconductivity in La${}_{1.675}$Eu${}_{0.2}$Sr${}_{0.125}$CuO${}_4$

C. R. Hunt, D. Nicoletti, S. Kaiser +3

We address the kinetic competition between charge striped order and superconductivity in La${}_{1.675}$Eu${}_{0.2}$Sr${}_{0.125}$CuO${}_4$. Ultrafast optical excitation is tuned to a mid…
